The thing is not what Jesus did or if it is possible for us to create in the future. Could we "cure" blindness? Sure we can, with robotic eyes and
development in medical sciences. Walk on water? Why not?
The question is about the very nature of time travel. Let's say that Jesus was from the future, then he must have had some reason to go back in time
to do something. Now, as Jesus arrived in the Year 0, he had already changed the timeline. The matter of our timespace would have been "The
Universe" + Jesus. We do not know yet what would happen if we sent back something, even back to yesterday.
Then there are two ways for time to exist - one path of time, in which time travel is impossible, and branched time, in which time travel is
possible.
If time is the former, then Jesus can not go back in time. We must assume that he had a reason for going back, but if he really changed something,
then he wouldn't have any reason in the future to go back, thus he did not travel in time in the first place.
In the latter it really doesn't matter, because branched time creates different timelines in every instant. He went back and changed something - so
what? There are infinite of possible futures, so changing anything in the past would only create another future (which most likely already exists),
not change anything.
